Ingredients
4 beets, medium roasted, cooled, peeled, and sliced
1 cup cider vinegar
1 cup water
⅓ cup granulated sugar
1 tsp. kosher salt
¼ tsp. ground mustard, (dry)
5 whole black peppercorns
Preparation
Bring the vinegar, water, sugar, salt, and mustard to a boil in a medium saucepan, stirring until sugar is dissolved. Simmer for a few minutes; take off the heat and allow to cool a bit.
Add peppercorns and beets to a clean glass jar with a tight fitting lid. (This particular recipe fits nicely into a 1 liter sized jar.) Pour the brine in, covering all the beets.
Cover and set aside for several hours (or up to 24), then transfer to the refrigerator.
